5 Advanced Setup
The VG4-100 Series camera module normally provides an optimal picture without the need for
further adjustments. Advanced setup options, however, are available for obtaining the best
results from the camera under special circumstances. There are two upper level On-Screen
Display (OSD) menus: the Main menu and the Install menu.
The Main menu allows you to select and setup the picture enhancement functions. The Install
menu allows you to set the camera ID, focus and synchronization settings. The Main and
Install menus have settings that you can select directly or open to submenus for a more
detailed setup.
